Well, no. Inside the drive, it automatically detects weak sectors and re-maps them on the fly. I think it's riskier to constantly move data back and forth than it is to just keep a good set of backups so you can recover from the (inevitable) failure.
I'd also suggest a very nice bit of software called SMART Reporter, which is free and available from VersionTracker. It'll keep you informed as to the SMART status of the drive, which *might* (no guarantee) give you some advance warning of drive failure. Hopefully.
